when trying to start, the starter will kick the drive gear for a second and then the starter will just keep running unengaged.....i've taken the drive gear out and it seems fine-no wear,retracts by itself...very few hours on this sportsman. could the drive gear on the starter be bad anyway.with the drive gear out the starter whirls away...i don':nervous:t know anything else it could be....it will start when hand cranked,...thx
